Andrews [41]

Answer:

0.978 M

Explanation:

Given data

Mass of luminol (solute): 13.0 g

Volume of the solution = volume of water: 75.0 mL = 0.0750 L

We can find the molarity of the stock solution of luminol using the following expression.

M = mass of solute / molar mass of solute × liters of solution

M = 13.0 g / 177.16 g/mol × 0.0750 L

M = 0.978 M
